Windows NT LAN Manager (NTLM) Authentication Limitation
Dell OpenManage Power Center supports Kerberos SSO for Windows domain user authentication. To enable this
feature, Power Center is configured to support the Windows integrated authentication option which includes two
authentication mechanisms: Kerberos and NTLM .
NTLM is not supported in Power Center. If the client’s web browser uses NTLM to authenticate domain users for Power
Center, there are some limitations.
The web browser displays a message box requiring a Windows user name and password.
• If you click OK after entering a user name and password, whether the information is correct or not, the Power
Center login page displays and requires you to authenticate through the login page.
• If you click Cancel, an HTTP Status 401 failure displays, and you cannot log into Power Center.
See Troubleshooting for more information on how to handle this issue.
Logging Out
To log out of Dell OpenManage Power Center when not logged in through Kerberos SSO, click Logout at the upper right
corner of the management console.
When logged in through Kerberos SSO, close the web browser or the Power Center management console to log out.
Clicking Logout will not work.
